Read the passage given below and answer the following questions:
The amount of moisture that leather adsorbs or loses is determined by temperature, relative humidity, degree of porosity, and the size of the pores. Moisture has great practical significance because its amount affects the durability of leather, and in articles such as shoes, gloves and other garments, the comfort of the wearer. High moisture content accelerates deterioration and promotes mildew action. On the other hand, a minimum amount of moisture is required to keep leather properly lubricated and thus prevent cracking. The study indicates that adsorption of moisture by leather is a multi- molecular process and is accompanied by low enthalpies of adsorption. Further at 75-percent relative humidity, the adsorption is a function of surface area alone. Untanned hide and chrome- tanned leathers have the largest surface areas. The leathers tanned with vegetable tanning materials have smaller surface areas since they are composed of less hide substance and the capillaries are reduced to smaller diameters, in some cases probably completely filled by tanning materials. This process of tanning occurs due to mutual coagulation of positively charged hide with negatively charged tanning material. The result of the study indicated that untanned hide and chrome-tanned leather absorb the most water vapour.
In these questions a statement of Assertion followed by a statement of Reason is given. Choose the correct answer out of the following choices.
Assertion (A): Adsorption of moisture by leather is physisorption.
Reason (R): It is a multimolecular process and is accompanied by low enthalpies of adsorption.
  • a)
    Assertion and reason both are correct statements and reason is correct explanation for assertion.
  • b)
    Assertion and reason both are correct statements but reason is not correct explanation for assertion.
  • c)
    Assertion is correct statement but reason is wrong statement.
  • d)

Assertion and Reason Analysis:

Assertion (A):
Adsorption of moisture by leather is physisorption.

Reason (R):
It is a multimolecular process and is accompanied by low enthalpies of adsorption.

Explanation:
- Adsorption of Moisture: The passage mentions that the adsorption of moisture by leather is a multi-molecular process. This means that moisture is being physically adsorbed onto the surface of the leather rather than chemically bonded.
- Physisorption: Physisorption is a type of adsorption where molecules are held on the surface of a material by van der Waals forces. This type of adsorption is typically characterized by low enthalpies of adsorption, as mentioned in the reason.
- Low Enthalpies of Adsorption: The reason states that the adsorption of moisture by leather is accompanied by low enthalpies of adsorption, which is a characteristic of physisorption.
- Therefore, based on the information provided in the passage, the assertion that adsorption of moisture by leather is physisorption is correct. The reason provided also supports this assertion by mentioning the multi-molecular process and low enthalpies of adsorption associated with the adsorption of moisture by leather.

Therefore, the correct answer is:
a) Assertion and reason both are correct statements and reason is correct explanation for assertion.
